Patented May 3, 1932 units!) STATES PATENT @FFECE JOHN T. CORLEY, OF PROVIDENCE, RI-IODE ISLAND, ASSIGNOR TO J. M. BAKER PATTERN COMPANY, INC., OF PROVIDENCE, RHODE ISLAND, A CORPORATION OF RHODE ISLAND TURRET STANIDIPIPE AND MANUFACTURE THEREOF Application filed November 15, 192$,fieria1 No. 407,348. Renewed September 22, 1931.

This application is a continuation in part of copending application Serial No. 240,293, filed December 15, 1927 for turret standpipe for fire hose.

The invention relates to an improved construction of turret standpipe for fire hose, and has for its object to provide in such a device a turret body member in which is swivelled a turret head member, this head member being of Y-shape with inturned end portions between which end portions is pivotally mounted the nozzle, whereby a universal movement of the nozzle is permitted to set the same in different directions.

The invention includes the forming of a face plate separate from the inturned ends of the Y and the securing of this face plate in position by molding or other bonding means, which construction greatly facilitates the threading and finishing of the inturned ends of the Y-shaped turret head.

With these and other objects in view, the invention consists of certain novel features oi? construction more fully described in the detailed description iiollowinp' in conjunction with the accompanying drawings, and paiticularly pointed out in the appended claims.

In the drawings:

Fig. 1 is a plan view of my improved device, partly broken away to show the swivelled joint between the nozzle section and the Y-shaped member;

Fig. 2 is a plan view of the Y-shaped head member, partly broken away, to showthe separate :tace plates;

Fig. 3 is an enlarged detail in section showinn the swivelled oint of Figure 1;

Fig. t is a view of the back of the face section; and

Fig: 5 is an enlarged section thereof.

It is found in practice in the manipulation of fire hose for fighting fires of advantage to provide a turret standpipe having a. Y- shaped head member and to so mount the nozzle in the Y-shaped turr t head member that the nozzle may be supported at any desired elevation relative to the head member and retained in such adjusted pos tion without the necessity of being held by the firemen,

thus leaving them free for other work; it has also been found ditlicult to out screw threads on the periphery of the inturned ends of the (shaped head member for the recep tion of the binding nuts, and to obviate this constructhmal difiiculty, I have formed separate and independent end plates which have been previously finished and threaded and have bonded these end plates into the ends of the turret head member, preferably when the latter is cast, thereby materially reducing the time and labor necessary for the finishing operation of this portion of the device; and the following is adetailed description of the present embodii'nent of my invention, showing; one arraiug'ement of parts whereby these advantageous results may be accomplished:

WVith reference to the drawings, 10 designates the turret body member of my i1nproved device, which is provided at one end with a double hose connection as at 11, and at its opposite end. with aswivelled oint portion 12 in which is-rotatably mounted the turret head member 13 and which is rotatably held therein by means of a nut 14;. This turret head member is preierabl'y Y- shaped, the ends of the branches being turned inwardly towards each other as at 15, and each otthese interned ends is provided with a separate end plate 16 which is formed in CliSl-I shape, see Figures 4: and 5.

This end plate has a peripheral flange 17 which is threaded on the outer surface and also on its inner surface. This plate also has an inner flange 19 threaded on both its inner and outer surfaces; These internal threads serve to roughen the surface to lock the plate in the ends of the Y when the metal is flowed around the same in casting the plates in these ends. These plates ar finished prior to being cast into position in the turret head and by this construction, it will be seen that the :finh tins; of this Y-shaped turret head is greatly facilitated, as owing to its shape it is very hard to handle and special tools and fixtures must be provided with which to finish the surface and thread the periphery, the cost oi: which is greatly reduced by my im proved arrangement of forming separate finished end plates and bonding them in position in the Y-shaped turret head by a molding operation.

These plates may be secured by other than a molding operation if desired; thus, the invention contemplates, in certain instances, welding the end plates to the inturned ends of the Y by first securely positioning the end plates and the Y in proper fixed relationship, and then welding by the addition of welding material in the vicinitj of the joint to firmly secure the end plates to the head member. If desired, the inside juncture of the end plates and the end of the head member may be finished by adding welding material and Y removing the excess thereof, or 1n any other suitable way.

The swing joint member of this device has oppositely turned inlet portions 21, the ends of which are faced and in some cases grooved to receive a packing ring 22 and these ends are flanged as at 23 to receive a nut 24 by which these ends are bound against the faces of the turret head, the packing members 22 serving to prevent leakage and also functioning as a friction element to retain the nozzle 25 in any adjusted position without the necessity of being supported by the firemen who may leave this device when once set in position to continue its work while they busy themselves in other directions. A packing ring 26 is provided between the flange 23 and the nut 24.

My improved turret standpipe is very practical in its construction and operation and serves as an effective fire fighting device requiring the minimum amount of attention from the firemen. The use of previously finished end plates which are molded or welded to the inturned ends of the Y member reduces the cost of manufacture of turret standpipe by eliminating thenecessity for special lathes and other machinery heretofore necessary for finishing the end plates so as to receive the inlet portion 21 and the lock nuts for securing the inlet portion 21 in place.

lVhile I have described specific methods and constructions for accomplishing these desirable results, desired changes in the method and arrangement of parts to fit the needs of particular standpipe designs may obviously be made without departing from the spirit and scope of the invention as defined in the appended claims.

I claim:

1. A tubular Y-shaped head member for a turret standpipe, comprising a pair of end plates each having a finished working face in aligned parallel relationship, the back of each plate having projections, and a Y-shaped body member having inturned ends molded in alignment with said plates and in engagement with said back and projections.

2. In a fire hose turret standpipe which has a turret body, a tubular Y-shaped head member of cast metal shaped to be attached to said body at one end thereof and having inturned ends facing each other, a separate face plate for each of said ends having a rearward projection about which the stock of said head member is molded to bond the two together, a nozzle having oppositely outturned inlet ends pivotally mounted between said opposite face plates of said inturned ends of the Y-shaped head member, and a nut screwed onto said threaded surface of the face plates of the Y for operatively securing the inturned ends of the Y-shaped head member and the outturned ends of the nozzle together.

3. A tubular Y-shaped head member for a turret standpipe, comprising a pair of end plates each having a finished working face in aligned parallel relationship, the back of eachplate havingroughened projection s,'and a (shaped body member having inturned ends molded in alignment with said plates and in engagement with said back and roughened projections.

In testimony whereof I affix my signature.
